Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental b ....Fire management of complex rehabilitated forests - quantifying and understanding spatial variability of forest structure and fuels. Up to 5 million ha of forest is burnt by bushfire in Australia in severe fire years. The cost of fire suppression in 2002/3 in WA was in excess of 12 million dollars. Consequently, development and application of technologies and knowledge for enhancing fire management and reducing wildfire risk is of high priority and substantial economic, social and environmental benefit. The opportunity to conduct experimental fires across a complex landscape will enable calibration and development of technologies not previously possible. This research will define the way prescribed fire is used to integrate young rehabilitated forest into management of the broader landscape and develop more cost-effective tools for fire management.Read moreRead less
Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspr ....Population dynamics and genetic variation of plants with contrasting fire responses. We combine the traditional concerns of population viability analyses with the modern techniques of DNA fingerprinting for precise genotyping of individual plants and their seeds. We expect major breakthroughs in our understanding of how fire-killed species have survived thousands of years of frequent burning by Aborigines (by identifying seeds dispersed long distances from burnt parents); how paternity of offspring changes over the lifespan of plants which retain their seeds for many years; at what age within-plant genetic variation is at a maximum as a guide to optimal fire management; and the extent that deleterious somatic mutations explain low seed set among long-lived species.Read moreRead less
Understanding the health effects of landscape burning and biomass smoke in Australian towns and cities. Bushfires are increasingly affecting Australian towns and cities directly and indirectly from episodes of severe air pollution. An approach to manage bushfires is to reduce fuel loads by setting planned fires under stable weather conditions, yet this strategy is controversial because of community concerns about ecological sustainability and negative health impacts from smoke. The relative im ....Understanding the health effects of landscape burning and biomass smoke in Australian towns and cities. Bushfires are increasingly affecting Australian towns and cities directly and indirectly from episodes of severe air pollution. An approach to manage bushfires is to reduce fuel loads by setting planned fires under stable weather conditions, yet this strategy is controversial because of community concerns about ecological sustainability and negative health impacts from smoke. The relative importance of air pollution from planned and unplanned bushfires vs. wood heaters, agricultural burning and other sources of air pollution will be determined. Our study will enable evidence-based bushfire smoke management, help formulate national air quality standards and shape policies regarding biomass smoke and bushfire management.Read moreRead less
An unprecedented opportunity to quantify biodiversity recovery after major wildfire. Recent fire disasters in southern Australia emphasise that wildfire is one of the major social, economic and ecological issues facing the nation. Biodiversity loss and environmental degradation are also substantial national issues.

Recent fire disasters in southern Australia emphasise that wildfire is one of the major social, economic and ecological issues facing the nation. Biodiversity loss and environmental degradation are also substantial national issues. The outcomes and new understanding obtained from this project will have enormous rural, regional, national and international benefits through developing better informed, and ecologically sustainable, principles and practices for biodiversity conservation, vegetation management, and fire management. It also will guide natural resource managers such as national park staff and state forest managers in best practice methods to manage post-fire ecological recovery on land under their jurisdiction.

The key aim of this study will be to quantify changes in vertebrate biota (reptiles, birds, arboreal marsupials and terrestrial mammals) within vegetation types subject to alternate burning strategies. The investigation will provide critical new knowledge for use in fire management, vegetation management and biodiversity conservation within national parks, state forests and similar types of land.Read moreRead less
Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of popula ....Quantifying long-distance seed dispersal and its role in the metapopulation dynamics of plants with contrasting life histories. This work will contribute to the assessment of best fire-management practices, enabling land managers to compare current fire practices against those required for conservation of genetic resources. Our quantification of Long distance seed dispersal (LDD) among species with different life history attributes will be a major theoretical contribution to the fields of population ecology and population genetics. LDD is also imperative if species are to survive the major shifts in climate projected under modelled climate change scenarios - species without effective LDD may have a greater probability of extinction due to climate change. Assessing LDD enables quantification of this significant aspect of the threat of climate change to biodiversity.Read moreRead less
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An ....Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less

Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project ....Movement ecology of granivores: informing fire management of savannas. This project aims to examine the decline in granivorous finches across north Australia and test the hypothesis that an increasingly nomadic lifestyle, associated with tracking grass seed availability over larger spatial scales, is the cause. The project also aims to evaluate how fire affects rangeland functioning, particularly grass diversity, to improve fire management of tropical savannas in northern Australia. This project will provide new tools and technologies that will monitor mobile small vertebrates. Expected outcomes will improve the understanding of tropical savanna functioning and fire management. The research aligns with ‘savanna burning’ methodologies and carbon sequestration goals in north Australia.
